[mapserver-users] undesired pattern with getLegendGraphic

[Steve.Toutant at inspq.qc.ca]

Hi,
My problem is with the CLASS of a WMS layer. Using Cascading 
GetLegendGraphic I get the legend defined on the server side, a triangle 
with a label. But I don't want to use this legend so I created a CLASS 
definition for the layer so I get only a triangle.
But instead of returning a single triangle, I get several triangles in the 
image. See attached files
I can't find what can cause this behavior. 
Here is the symbol definition and the mapfile
SYMBOL
        NAME    'triangle'
        TYPE    VECTOR
        FILLED  TRUE
        POINTS
                0       1
                .5      0
                1       1
                0       1
        END 
END

LAYER
NAME "fire"
TYPE RASTER
STATUS ON
CONNECTION "http://.../cgi-wms/mapserv?map=fire"
CONNECTIONTYPE WMS

METADATA
        "wms_srs"             "EPSG:900913"
        "wms_name"            "fire"
        "wms_title"           "fire"
        "wms_server_version"  "1.1.1"
        "wms_format"          "image/png"
END

CLASS
        NAME "fire"
        STYLE
                SYMBOL  "triangle"
                SIZE 15
                COLOR 178 34 34
                OUTLINECOLOR 144 0 0 
        END
END 
END

Thanks for your help
Steve
